Abstract
A method detects an unreachable endpoint in a voice over IP network operating according to standard protocol. The endpoints include a first endpoint as a call originator and a second endpoint as a VoIP destination. The endpoints are connectable via a soft-switch. After each call, a check is performed to determine whether the second endpoint responded to the call. If the second endpoint did not respond to the call, a non-call related message found in the standard protocol is sent from the soft-switch to the second endpoint. If the second endpoint does not respond to the non-call related message, the second endpoint is deactivated so that further calls are not
